valve springs

What valve springs should I run with a 556 lift and 224 at .050 duration hydraulic roller??

Comp 926 941??

Depends on several factors...... but in most street cars at low to moderate boost levels.... I think the consensus is around 130 - 140 lbs on the seat.
I have a roller cam very close to yours.....542 lift.....224-222...and i run 150lb valve springs, and im very happy with set up :smile:
